Title: Video tape recorder
Inventor: SASAKI HIDEMI
IPC: G11B15/665
Filed: 1987-10-19
Abstract: PURPOSE:To recede a slant guide member during drawing a tape and to correctly position it to a prescribed position after completing the draw of the tape by providing freely turnably a slant guide member to a prescribed position. CONSTITUTION:By providing freely turnably a slant guide member to a prescribed position, slant guide members 90A and 90B are receded during drawing the tape while they are fallen and after the drawing the tape is completed, the slant guide members 90A and 90B are raised in a tape loop. Thus, the moving channel, etc., to move the slant guide member from a cassette mouse part up to the prescribed position near a rotary head drum are made unnecessary and when the moving channel is restricted by the arrangement position of a rotary head drum, a large effect can be expected. Since the slant guide member can be freely turnably provided with a play and at the time of rising the member can be supported only with a supporting member fixed to a device main body, the member can be correctly positioned by the supporting member.
